LP/Gauge/Monitor

[Pete & Linda]

I have a difference in the reading of my LP Monitor inside and the gauge outside on the tank. Don't they use the same sending unit? Any ideas?

Just a guess but it could be in gauge calibration because even after you have the tank "filled" it can't contain any more than 80% of its capacity. I wonder if one gauge is calibrated for this and the other is not?

Thanks for starting this topic. I am behind the curve on this.

My indoor monitor only has 3 settings. It reads empty right now. The outside dial guage on the tank is below half, and almost down to one-quarter. So I guess this means I am below one-third so the inside monitor says empty.

Inspected the dial guage today. Looks like it pegs at E on the left side. I can understant that. The right side says F for full. But the dial goes further to the right past F and in small letters say 85 then 90.

My tank is 2008 so this is not opd valve issue. It is just that the dial guage will let you know that the tank was overfilled (over 80%).

All this is probably a little more than all I know about propane guages in motor homes. I am a new Class C owner.
